Register 12: Main Oscillator Control (MOSCCTL), offset 0x07C
This register provides control over the features of the main oscillator, including the ability to enable
the MOSC clock validation circuit. When enabled, this circuit monitors the energy on the MOSC
pins to provide a Clock Valid signal. If the clock goes invalid after being enabled, the part does a
hardware reset and reboots to the NMI handler.

Description
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
Clock Validation for MOSC
When set, the monitor circuit is enabled.
